To all whom it may concern:

Be it known that 1, Jules F. Pin'non, of Gly'nrich, in the county of New Gestie and State of -Deiaware, have invented certain new and useful Improvements in Rolling- Machines, whereof the following is s specification, reference being had to the accompanying drawings. v

The invention reietes more particularly to a rolling machine adapted to exert a rolling and stretching pressure against the 'outer face of e tu oe of fiber or similar material mounted on a mandrel.

An object of the invention is to provide :2 roiling; machine of the shove character, wherein the rolling pressure rosy be exerted against the materiel on the mandrel at opposed points hy roiiswvhich are so set es to move mandrel, together with its enveio'ping euhe endwise through the mechine.

Fig. \7 is is horizontal sectional view through "the head showing in plan one o of too edgustebie hearings and the roii supported thereby.

The invention consists prinieriiy in supporting frame on which is mounted the heed of the machine. Located within this heed and disposed in equal angular positions about the axis of the heed, are three pressure roiis which are adopted to exert e surface pressure against the tube which is to he treated in the machine. These roiis which are driven by suitable mechanism ore each mounted in hearings which .rney he adjusted redieiiy of the supporting head, and menus by weyoi.

piste 23. U1 1 is provided for simultaneously adjusting e11 of the rolls. The tube to be treated, after passing between the rolls, is received by e guiding member, and the rolls, as they operate upon the tube. not only exert pressure against the some, but feed the tuheendwise through the machine.

Referring more in detail to the drawings,

the improved roiling machine consists of 21 supporting frame 1, which may he of any desired construction. pointing frame is head 2, which, as herein shown, is in the form of a bracket 3, having a. hose secured to the frame by bolts 5. Bolted to bracket 3, is a cylindrical housing 6, seid housing; heino secured'hy means of hoits 7. i

Located centrally i the housing" are three roiis 8, 9, and 10, SE3 .0 T, 3W

Mounted on this sup- $79 under 7s 5 formed in Fif V Be UQLT pinion 52%, threaded into too 'drels to loosen the same from the it will be wheel in the opposite direction results in a movement of these bearings radially of the,

housing and toward the axis thereof.

- Connected with ,each roller shaft 11, by a universal joint, is a link 25, which linltsare in turn connected by similar un versal oints with stub shafts 26, each of which carries a gear i'nion 27. Pinions 27, mesh with gear whee 28, integrally formed on sleeve 29, which is mounted in bracket 30, carried by the main frame 1. The stub; shafts are also journaled in said bracket 30. Extending through sleeve 29, is a tubular support 31, which is secured to sleeve 29, by means of set-screw 32. The outer end of this tubular support-is flared as at 33, so as to form a tapered guiding surface for the tube to be rolled. Sleeve31, may, however, be replaced by similar sleeves of difl'erent bore, so that the machine may be adapted for rolling tubes of various diameters. I

In Fig. III, of the drawings, I have shown a mandrel 34, on which a tube 35, has been formed. The mandrel and tube are fed to the rolls through opening 36, 1n bracket 3. This tube may be made of fiber or similar material, and after drying, adheres very closely to the mandrel. One of the urposes of the present machine is to roll an stretch these fiber tubes on the mandrels in order to facilitate their removal from the same.

In operation, the rolls first are adjusted so that they will contact with the tube on the mandrel, and press against the outer surface thereof at the opposed points. The amount of pressure exerted against the tube is readily determined and varied by the hand wheel 24, which adjusts all of the rolls simultaneously toward and from the center of the housing supporting the rolls. The

rolls are rotated by a gear wheel 37, which" is splined to the sleeve 29, and meshes with a inion 38 on a main shaft carrying a pulley 39. After the rolls are put in operation the mandrel and tube are fed rolls through opening ,36, and through therolls enter the tubular guide 31, finally passin out through the same. The rolls, as clear y shown in the drawings, are set at an angle and, therefore, their rotation tends to feed the mandrel and tube through the machine and causes their ejection through the tubular guide'31.

While the rolling machine has been described as fiber tubes formed and dried on steel manmandrels, obvious that the machine may be after passing rolls into said guide.

to the particularly adapted for rolling used for other purposes, and that the detailsof construction and the arrangements of parts may be varied without departing from the spirit of the invention as setforth in the appended claims.

Having thus described my invention, .1 claim:

1. In a rolling machine, the combination of a series of opposed pressure rolls, means for rotating said rolls, means for simultaneously adjusting the said rolls toward and from a point centrally disposed relative to the rolls, and a tubular guide disposed beyond the rolls having its axis in line with sa d central point, whereb a tube passing through the rolls enters sald tubular guide, and is guided thereby, said tubular guide having a tapered guiding surface at its end for directing the tube passing through the 2.
